    Količina memeorije potrebna za prikaz slike u rezoluciji 1024x768 u 24 bitskom režimu je (red veličine):

    • A.

      2 MB

    • B.

      20 MB

    • C.

      200 KB

    • D.

      2 KB

    Correct Answer
    A. 2 MB
    Explanation
    The resolution of the image is given as 1024x768. In a 24-bit color mode, each pixel requires 3 bytes (8 bits per color channel). So, the total memory required to store the image can be calculated as 1024 x 768 x 3 bytes = 2,359,296 bytes. Converting this to megabytes, we get approximately 2 MB. Therefore, the correct answer is 2 MB.

    • D.

      DVI-I

    Correct Answer
    C. VGA
    Explanation
    CRT monitors use the VGA connector to receive signals from the video card. VGA (Video Graphics Array) is a standard analog video connection that was widely used before the advent of digital connections like DVI and HDMI. It consists of a 15-pin connector that carries the video signal from the video card to the monitor. CRT monitors have been largely replaced by LCD and LED monitors, but VGA is still commonly used for connecting older devices or for compatibility with legacy systems.

    Učestanost prekidanja struje u primaru invertorskog transformatora je (red veličine):

    • A.

      50 kHz

    • B.

      5 Hz

    • C.

      50 Hz

    • D.

      50 MHz

    Correct Answer
    A. 50 kHz
    Explanation
    The frequency of power interruptions in the primary side of an inverter transformer is typically in the range of kilohertz (kHz). This is because inverters operate at high frequencies to convert DC power to AC power, and any interruptions in the primary side would affect the output AC power. Therefore, a frequency of 50 kHz is a reasonable estimate for the frequency of power interruptions in the primary side of an inverter transformer.

    • A.

      Konstantan jednosmerni signal

    • B.

      Impulsnog tipa

    • C.

      Testerasti signal

    • D.

      Sinusnog tipa

    Correct Answer
    B. Impulsnog tipa
    Explanation
    The correct answer is "impulsnog tipa". The explanation for this is that an impulsnog tipa signal refers to a pulse signal, which is a type of signal that consists of a series of pulses or brief bursts of energy. In the context of a power supply circuit, using a pulse signal to control the base voltage of a transistor helps to stabilize the voltage by providing precise and controlled bursts of energy. This allows for more efficient regulation of the voltage and helps to prevent fluctuations or variations in the output.

    The correct answer is "Katoda I anoda." The explanation for this answer is that inside the cathode ray tube (CRT) monitor, there are two important components: the cathode and the anode. The cathode emits electrons, while the anode attracts and accelerates these electrons towards the screen, creating the images we see on the monitor. Both the cathode and the anode play crucial roles in the functioning of the CRT monitor.

    Ako je snaga stepena za napajanje dekarisana na 400W, a na vodu od 12V može da podrži struju od 18A, maksimalna snaga za potrošače koji zahtevaju napon od 12V je

    • A.

      216 W

    • B.

      324 W

    • C.

      400 W

    • D.

      144 W

    Correct Answer
    A. 216 W
    Explanation
    The given question provides information about the power of a power supply unit (PSU) and the current it can support for a 12V load. The power formula is P = IV, where P is power, I is current, and V is voltage. We are given that the PSU can support a current of 18A for a 12V load. By substituting the given values into the formula, we can calculate the power: P = 18A * 12V = 216W. Therefore, the maximum power for consumers requiring a 12V voltage is 216W.

    Formater laserskog štampača:

    • A.

      Je odgovoran za transport papira

    • B.

      Kontroliše stanje fotosenzora

    • C.

      Obrađuje ASCII podatke o slici

    • D.

      Kontroliše mikro senzore

    Correct Answer
    C. Obrađuje ASCII podatke o slici
    Explanation
    The correct answer is "obrađuje ASCII podatke o slici". This is because the question asks for the function of the formatter in a laser printer. The formatter is responsible for processing ASCII data about the image, which means it converts the image data into a format that the printer can understand and print. The other options mentioned, such as transporting paper, controlling photosensors, and controlling micro sensors, are not the primary functions of the formatter in a laser printer.

    . U toku faze prenošenja tonera na papir, prenosni (transfer) valjak

    • A.

    • B.

      Odstranjuje višak tonera

    • C.

      Zagreva toner

    • D.

      Odstranjuje višak tonera

    Correct Answer
    A. Je priključen na pozitivni napon
    Explanation
    The correct answer is "je priključen na pozitivni napon" because during the toner transfer phase, the transfer roller needs to be connected to a positive voltage in order to attract the toner particles from the drum onto the paper. This positive charge helps in the efficient transfer of toner and ensures that the excess toner is removed from the roller, resulting in a clean and accurate printing process.

    Ukoliko se na CRT monitoru pojavljuje horizontalna bela linija kvar treba tražiti u

    • A.

    • B.

      Horizontalnom stepenu

    • C.

    • D.

      Video stepenu

    Correct Answer
    A. Vertikalnom stepenu
    Explanation
    The correct answer is "Vertikalnom stepenu" (Vertical stage). This is because the question is asking about a horizontal white line appearing on a CRT monitor, and the issue is likely related to the vertical stage of the monitor. The vertical stage is responsible for controlling the vertical movement of the electron beam that creates the display on the screen. If there is a problem with this stage, it can result in various display issues, including horizontal lines. Therefore, the fault should be sought in the vertical stage.

    • D.

      Horizontalnom stepenu

    Correct Answer
    C. Losim kontaktima skretnih kalemova i stampane ploce
    Explanation
    The correct answer is "Losim kontaktima skretnih kalemova i stampane ploce" which translates to "Poor contacts of deflection coils and printed circuit board." This suggests that if a vertical white line appears on a CRT monitor, the problem may be due to poor contacts between the deflection coils and the printed circuit board.

    • C.

      400-700nm

    • D.

      980-1250nm

    Correct Answer
    C. 400-700nm
    Explanation
    The visible spectrum refers to the range of light that is visible to the human eye. It ranges from approximately 400 to 700 nanometers (nm). This means that light with wavelengths shorter than 400 nm (such as ultraviolet light) and longer than 700 nm (such as infrared light) cannot be seen by the human eye. Therefore, the correct answer is 400-700nm.

      Cijan, magneta, zuta

    Correct Answer
    A. Crvena, plava, zelena
    Explanation
    The correct answer is "crvena, plava, zelena" because these are the primary (additive) colors used in monitors. These colors can be combined in different intensities to create a wide range of colors on the screen. By mixing red, blue, and green light, the monitor can produce all other colors that we perceive.

    • D.

      250MV

    Correct Answer
    B. 25KV
    Explanation
    The correct answer is 25KV. The question is asking about the voltage of the anode in a CRT monitor. The anode voltage in a CRT monitor is typically very high, often in the kilovolt range, to accelerate the electrons and create the necessary energy for the display. Therefore, 25KV is the most suitable answer as it represents a high voltage value.
